Patients, staff and displaced people left Gaza’s largest hospital Saturday, health officials said, leaving behind only a skeleton crew to care for those too sick to move and Israeli forces who had taken over the facility earlier in the week.

The exodus from Shifa Hospital in Gaza City came the same day internet and phone service was restored to the Gaza Strip, ending a telecommunications blackout that forced the United Nations to shut down critical humanitarian aid deliveries because it was unable to coordinate its convoys.

In the south, an Israeli airstrike hit a residential building on the outskirts of the town of Khan Younis, killing at least 26 Palestinians, according to a doctor at the hospital where the bodies were taken.

Israel’s military has been searching Shifa Hospital for traces of a Hamas command center that it alleges was located under the building — a claim Hamas and the hospital staff deny – and urging the several thousand people still there to leave.

On Saturday, the military said it had been asked by the hospital’s director to help those who would like to leave do so by a secure route.

The military said it did not order any evacuation, and that medical personnel are being allowed to remain in the hospital to support patients who cannot be moved.

But Medhat Abbas, a spokesman for the Health Ministry in Hamas-controlled Gaza, said the military had ordered the facility cleared, giving the hospital an hour to get people out.

Later, Dr. Ahmed Mokhallalati, a Shifa physician, said on social media that there were some 120 patients remaining who were unable to leave, including some in intensive care and premature babies, and that he and five other doctors were staying behind to care for them.

Israel has signaled plans to expand its offensive south while continuing operations in the north. In Khan Younis, the attack early Saturday hit Hamad City, a middle-class housing development built in recent years with funding from Qatar. In addition to the 26 people killed, another 20 were wounded, said Dr. Nehad Taeima at Nasser Hospital.

Israel rarely comments on individual strikes, saying only that it is targeting Hamas and trying to avoid harm to civilians. In many of the Israeli strikes, women and children have been among the dead.

The war, now in its seventh week, was triggered by Hamas’ Oct. 7 attack in southern Israel, in which militants killed about 1,200 people, mostly civilians, and abducted some 240 men, women and children.

More than 11,400 Palestinians have been killed in the war, two-thirds of them women and minors, according to Palestinian health authorities. Another 2,700 have been reported missing, believed buried under rubble. The count does not differentiate between civilians and combatants, and Israel says it has killed thousands of militants.

The U.N. has warned that Gaza’s 2.3 million people are running critically short of food and water, but it was not immediately clear when the agency for Palestinian refugees, known as UNRWA, would be able to resume the delivery of aid that was put on hold Friday.

The Palestinian telecommunications provider said it was able to restart its generators after UNRWA donated fuel. The end of the communications blackout meant a return to news and messages from journalists and activists in the besieged enclave on social media platforms as service began to return late Friday night.

AID DRIES UP

Gaza’s main power plant shut down early in the war and Israel has cut off the electricity supply. That makes fuel necessary to power the generators needed to run not only the telecommunications network, but water treatment plants, sanitation facilities hospitals and other critical infrastructure.

Israel has barred entry of fuel since the start of the war, saying it would be diverted by Hamas for military means. It has also blocked food, water and other supplies except for a trickle of aid from Egypt that aid workers say falls far short of what’s needed.
